Specification of Letters Patent.

Patented Dec. 11, tuft.

Application filed January 3, 1913. Serial No. 739,999.

To all whom it may concern.-

Be it known that l[, Ennns'r lldlorruuson, a citizen of the United States, and a resident of East Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvementsin Machines for Serving Glass, of which the following is-a full, clear, and exact disclosure.

My invention. relates to devices employed for obtaining uniform molten masses of glass directly from "a flowing stream thereof,

and its object is to generally improve such devices and particularly to deposit the masses of glass directly into the molds or other receptacles without the necessity of sustaining the stream while the molds or receptacles are being changed. Briefly stated, my invention comprises a series of receptacles on molds carried on a movable support, such as a rotatable table, the edges of the moldshaving sharp edges, each of which constitutes one of the cutting members of the shearing device for severing the flowing stream of glass.

For a detailed description of one form of my invention, reference may be had to the following specification and to the accompanying drawing forming a part thereof, in

whlch: Figure 1 is a vertical sectional view of the carrier and cutting device, and showing the driving mechanism therefor in elevation Fig. 2 is a plan view thereof; and

Figs. 3 and 4. are detached sectional views showing the cutting device in two positions relativeto the receivers.

Referring to the drawing, the numeral 1 indicates the usual flow block which projects from a glass furnace or tank. 2 is a standard or frame upon whichthe rotatable mold carrier 3 is pivoted. The receivers or molds 4 are mounted on the carrier 3 and in this instance their sides, which contact with each other, converge toward the center of the carrier 3 on radial lines. The upper edges of the receivers 4 are beveled as shown at 5, so that when adjacent receivers come in contact, substantially sharp cutting edges are formed. between. the receivers, as clearly shown in Figs. 1 and 3.

A reciprocating cutting member or knife 6 is mounted upon a longitudinally slidable bar 7 which carries atits lower end a cam roller or follower 3 which contacts with the cam 9 on the horizontal shaft 10. The shaft '10 is connected with suitable driving mechanism, and in this instance carries the fast and loose pulleys 11 and 12 around'which may run a belt of the usual form.

The carrier 3 is advanced intermittently between the cutting operations and for this purpose the spindle 13, to the upper end of which the carrier 3 is fixed, has" attachedto its lower end a screw gear 14 which meshes with the screw pinion 15 mounted on the shaft 16. The shaft 16 also carries a slotted disk or star wheel 17 which cooperates with a pin or stud 18 projectingfrom a crank arm 19 on the shaft 10.

The cutting knife 6-and the edges of the receivers may be water-cooled should the same be found necessary.

The rotation of the shaft reciprocates the cutting element 6 when the receivers are at rest and the crank arm 19 is so upon the shaft 10 that when the kiii e 6 is out of operative contact with the edges 5 of the receivers 4, the carrier 3 and consequently the receivers will be advanced the requisite distance to bring the next one into position to cooperate with the cutting knife.

laced 1 By referrin to Figs. 1, 3 and 4, it will be seen that t e carrier 3 is so located in relation tothe flow-block 1, that the stream is diverted, then out and after being out, flows substantially into .the centerof the rece tacle. This is aided by reason of the motion of the cutting element 6, down the inclined surface 5 of a receiver 4, since the cutting element positively forces the upper portion of the stream away from the surface 5 and toward the normal path of flow, as indicated in Fig. 4. The same then moves so that the next succeeding receptacle is beneath the flow-block and the stream of glass is therefore drawn across the intervening edges of the receptacles. When the same become stationary the cutting knife descends and severs the -figlass, the lower cut-offend falling into the rst receptacle and the upper end into the next one, whence the above described cycle is repeated.

The receptacles .5 may be, themselves, molds in which the articles are formed, or may be receivers from which the glass may be transferred to molds to be pressed or blown.

Having thus described this form of my invention, I do not wish to be limited to the precise details of form and arrangement of parts illustrated, but what ll claim and desire to protect by Letters Patent is:
